Aequationes Mathematicae, 1972 Let \(\varphi\) be a positive non-decreasing real valued function defined on \([0, \infty)\), and let \(f\) be any real valued function defined on \([0, \infty)\). We say that \(f\) is \(\varphi\)-slowly varying if \(\varphi (x)[f(x+ \alpha)-f(x)] \to 0\) as \(x \to \infty\) for each \(\alpha\). We say that \(f\) is uniformly \(\varphi\)-slowly varying

A nonlinear theory for shells with slowly varying thickness [PDF]
, 2008 We study the $\Gamma$-limit of 3d nonlinear elasticity for shells of small, variable thickness, around an arbitrary smooth 2d surface.Comment: 6 ...

Neutrino interactions with a weak slowly varying electromagnetic field [PDF]
, 2000 We derive the effective action for processes involving two neutrinos and two photons at energies much below the electron mass. We discuss several applications in which one or both photons are replaced by external fields.

Slowly Varying Regression Under Sparsity
Operations ResearchBuilding Sparse and Temporally or Spatially Linked Regression Models The framework of slowly varying regression under sparsity addresses many problems in machine learning where the underlying model is sparse and varies slowly and sparsely. This includes problems with temporally or spatially varying structures.

Photon propagation in slowly varying electromagnetic fields
, 2016 We study the effective theory of soft photons in slowly varying electromagnetic background fields at one-loop order in QED. This is of relevance for the study of all-optical signatures of quantum vacuum nonlinearity in realistic electromagnetic ...

Relevance of the slowly-varying electron gas to atoms, molecules, and solids [PDF]
, 2006 Under a certain scaling, the electron densities of finite systems become both large and slowly-varying, so that the gradient expansions of the density functionals for the Kohn-Sham kinetic and exchange energies become asymptotically exact to order ...

Three-dimensional flows in slowly-varying planar geometries
, 2003 We consider laminar flow in channels constrained geometrically to remain between two parallel planes; this geometry is typical of microchannels obtained with a single step by current microfabrication techniques.

Finite VEVs from a Large Distance Vacuum Wave Functional [PDF]
, 1998 We show how to compute vacuum expectation values from derivative expansions of the vacuum wave functional. Such expansions appear to be valid only for slowly varying fields, but by exploiting analyticity in a complex scale parameter we can reconstruct ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.
